The anthology in question is Flashspec volume one, a collection of speculative flash fiction. In this case, that means stories which come in at less than 500 words. (So you can read them in a flash, see?)
You can order a copy online through the link. I have one copy with another on the way, and now that Hal 3 is done done done I'm going to start reading again.
The second volume has a reading period starting in April 2007, so what are you waiting for? Read up on the art of good flash fiction and get ready to submit!
